这是什么样的加密？ JavaScript/jQuery代码

好吧，我正在阅读一些我动手的文件，并且这个JavaScript文件具有此文件中使用的jQuery数组。

该代码是什么样的加密？

var _0xe66d=["\x53\x61\x79\x48\x65\x6C\x6C\x6F","\x47\x65\x74\x43\x6F\x75\x6E\x74","\x4D\x65\x73\x73\x61\x67\x65\x20\x3A\x20","\x59\x6F\x75\x20\x61\x72\x65\x20\x77\x65\x6C\x63\x6F\x6D\x65\x2E"];function NewObject(_0xa79fx2){var _0xa79fx3=0;this[_0xe66d[0]]= function(_0xa79fx4){_0xa79fx3++;alert(_0xa79fx2+ _0xa79fx4)};this[_0xe66d[1]]= function(){return _0xa79fx3}}var obj= new NewObject(_0xe66d[2]);obj.SayHello(_0xe66d[3])

well i was reading some files i got my hands on and this javascript file had this array that jQuery inside this file is using.

what kind of encryption is this code?

var _0xe66d=["\x53\x61\x79\x48\x65\x6C\x6C\x6F","\x47\x65\x74\x43\x6F\x75\x6E\x74","\x4D\x65\x73\x73\x61\x67\x65\x20\x3A\x20","\x59\x6F\x75\x20\x61\x72\x65\x20\x77\x65\x6C\x63\x6F\x6D\x65\x2E"];function NewObject(_0xa79fx2){var _0xa79fx3=0;this[_0xe66d[0]]= function(_0xa79fx4){_0xa79fx3++;alert(_0xa79fx2+ _0xa79fx4)};this[_0xe66d[1]]= function(){return _0xa79fx3}}var obj= new NewObject(_0xe66d[2]);obj.SayHello(_0xe66d[3])

您显示的输出看起来像是使用 obfuscator.io 。

去量身定制的代码仅在一定程度上起作用。

您可以肯定地使用

function NewObject(_0xa79fx2) {
  var _0xa79fx3 = 0;
  this.SayHello = function (_0xa79fx4) {
    _0xa79fx3++;
    alert(_0xa79fx2 + _0xa79fx4);
  };
  this.GetCount = function () {
    return _0xa79fx3;
  };
}
var obj = new NewObject("Message : ");
obj.SayHello("You are welcome.");

但是，这样的工具无法恢复原始变量或参数名称，因为在混淆过程中已替换了这些名称。而且没有办法取回这些。

The output you show looks like it was a result of using obfuscator.io.

Deobfuscating such a code works only to a certain degree.

You can for sure use a tool like deobfuscate.io. This results in this:

function NewObject(_0xa79fx2) {
  var _0xa79fx3 = 0;
  this.SayHello = function (_0xa79fx4) {
    _0xa79fx3++;
    alert(_0xa79fx2 + _0xa79fx4);
  };
  this.GetCount = function () {
    return _0xa79fx3;
  };
}
var obj = new NewObject("Message : ");
obj.SayHello("You are welcome.");

But such tools can't recover the original variable or parameter names because those have been replaced in the obfuscation process. And there is no way to get those back.
